Barry | Diana
Barry knew that Diana wouldn't have come to the party had she not wanted to -- that she wouldn't have come with him had she not wanted to. That didn't stop him from considering the alternative, even briefly. He was pleased that she had agreed to come with him. He truly did like her, he enjoyed her company.
"It's amazing how nicely I can clean up," he said, with a grin. He was happy with the suit he'd (Diana had) chosen. He felt rather dapper in it -- and he liked that it seemed to go well with what Diana happened to be wearing.
He nodded at Diana's question, "Yes, let's." It took a lot to get Barry drunk due to his metabolism, but he did like to drink every once in a while.
